DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A foundation pad for a wooden building as a basis of the present invention will be described below with reference to FIGS.

FIG. 1 shows a foundation pad 1. As shown in FIG. 2, the base pad 1 is interposed between a cloth base 2 and a wooden base 3 mounted and fixed thereon, and is a flat main body made of a metal plate. 4 and a gap forming protrusion 5. The gap forming protrusions 5 include a small-diameter protrusion 6 provided to be dispersed at appropriate intervals over the entire surface except for the central portion of the plate-shaped main body 4 and an anchor bolt 10 provided at the center of the plate-shaped main body 4. Large diameter projection 7 that can be inserted
Consists of These small-diameter projections 6 and large-diameter projections 7 project from the flat body 4 toward the cloth base 2 to form a substantially constant gap 9 between the cloth foundation 2 and the wooden base 3. And a cylindrical projection 8 having an annular wall integrally formed so as to protrude from the plate-shaped main body 4, and has a central portion penetrating therethrough.

When the foundation pad 1 having the above configuration is used, as shown in FIG. 2, the position of the anchor bolts 10 on the cloth foundation 2 and the position immediately below the wooden pillars 13 and the appropriate distance L besides the wooden pillar 13 The foundation pads 1 are arranged at intervals, and the wooden base 3 is arranged thereon. It is appropriate that the appropriate distance L is about 1 m at the maximum. When arranging the foundation pad 1, if necessary, the foundation pad 1 can be temporarily fixed to the upper surface of the cloth foundation 2 with concrete nails by using the small-diameter projection 6 of the foundation pad 1, or the wooden foundation 3 It can also be nailed to the bottom surface using the small diameter projection 6. Further, in the arrangement position of the anchor bolt 10, as shown in detail in FIG. 3, the anchor bolt 10 is passed through the large-diameter projection 7 and the anchor bolt hole 3 a of the wooden base 3,
The wooden base 3 is fixed to the cloth foundation 2 by fastening with the nut 14.

In the above-mentioned construction, charcoal powder is applied to the upper surface of the flat body 4 of the foundation pad 1 in advance, and then the wooden base 3 is placed thereon. It is possible to prevent dew condensation from occurring on the upper surface of the plate-shaped main body 4 due to the specific heat difference, and to prevent corrosion on the contact surface of the wooden base 3 with the foundation pad 1. Instead of applying charcoal powder at the time of construction, a lining layer having a specific heat close to that of wood may be previously formed on the upper surface of the flat plate-shaped main body 4 by thick film coating or the like.

In this manner, in a state where the wooden base 3 is placed on the cloth base 2 via the base pad 1 and supported, the load acting on the wooden base 3 is applied to the flat body 4 of the base pad 1 and the gap forming protrusion. 5 (6, 7), it is supported by the cloth foundation 2, so that a stable supporting state can be obtained while forming the gap 9 between the cloth foundation 2 and the wooden base 3. In addition, since air can freely flow between the gap forming projections 5 and 5 even in the portion of the base pad 4, air permeability can be ensured in any direction, and the thickness of the base pad 1 becomes more than necessary. It is possible to secure an opening area necessary for underfloor ventilation while making the gap 9 between the cloth foundation 2 and the wooden base 3 relatively small without being thick, and it is particularly effective in preventing the wooden base 3 from being corroded. .

Further, since the gap forming projections 5 are composed of a plurality of small-diameter projections 6 around the plate-shaped main body 4 and a large-diameter projection 7 at the center, a load is applied to the entire plate-shaped main body 4. Can be dispersed and supported, and the central large-diameter projection 7 can be attached to the anchor bolt 1
It can be used as a zero insertion hole. Further, since the gap forming projection 5 is formed by the cylindrical projection 8 having an annular wall formed integrally with the plate-shaped main body 4, a large supporting strength can be obtained with a small cross-sectional area. By dispersing them, it is possible to provide both support strength and air permeability.

Further, since the gap forming projections 5 (6, 7) are constituted by cylindrical projections 8 consisting of only annular walls and penetrate the central portion, dew condensation and the like are formed by the condensed water. (6,7)
There is no danger that the wooden base 3 is likely to corrode due to the moisture from the accumulated dew water, without inconvenience. In the case where there is no risk of dew condensation or the anchor bolt 10 is not inserted, the gap forming protrusions 5 (6, 7) may be constituted by a bottomed cylindrical protrusion 8.

Next, a preferred embodiment of the present invention will be described with reference to FIG. Pad 1 for foundation of this embodiment
In the above, the gap forming protrusions 5 are composed of a plurality of small-diameter protrusions 6 at four corners of the plate-shaped main body 4, a large-diameter protrusion 7 at a central portion, and a plurality of regions distributed therebetween. It is composed of a bowl-shaped protrusion 11. The small-diameter projection 6 is formed by a bottomed cylindrical projection 8 having an annular wall, and a through hole 1 is formed in the bottom wall 8a.
2 are formed. The large-diameter projection 7 is formed by opening most of the bottom wall 8a of the bottomed cylindrical projection 8 as a large-diameter through hole 7a through which the anchor bolt 10 passes.
The bowl-shaped protrusion 11 is constituted by a protrusion having an inclined peripheral wall integrally formed so as to protrude from the plate-shaped main body 4 toward the cloth base 2. A through hole 12 is formed in the center of the bottom.

In this embodiment, in a state where the wooden base 3 is mounted on the cloth base 2 via the base pad 1 and is supported, the load acting on the wooden base 3 in a normal state is a flat body of the base pad 1. 4 and gap forming projections 5 (6, 7, 1
Since it is supported by the cloth foundation 2 via 1), a stable supporting state can be obtained while forming a gap 9 between the cloth foundation 2 and the wooden base 3 in the same manner as in the above embodiment, and this foundation pad is also provided. Breathability is ensured even in one part. Further, in the present embodiment, when an impact load is applied during an earthquake or the like, the small-diameter projection 6 and the large-diameter projection 7 of the portion where the excessive load is applied bite into the cloth foundation 2 so that a bowl-like shape having an inclined peripheral wall is formed. The protrusion 11 is buffered and supported by the elastic deformation and ultimately the buckling deformation, and the excessive load is dispersed and absorbed, so that the wooden building can be prevented from being fatally damaged.

In the present embodiment, an example is shown in which both the small-diameter projection 6 and the large-diameter projection 7 composed of the cylindrical projection 8 and the bowl-shaped projection 11 are provided. Since the support rigidity is relatively large, a stable support state in normal times can be ensured. Therefore, only the plurality of bowl-shaped protrusions 11 may be dispersedly arranged on the entire surface of the flat body 4.

Next, regarding a second embodiment of the present invention,
This will be described with reference to FIG. In each of the above embodiments, the example in which the foundation pad 1 is interposed between the wooden base 3 and the cloth foundation 2 has been described. However, in this embodiment, the wooden pillar 13 is placed on the cloth foundation 2 and supported. In the structure, the foundation pad 1 is interposed between the wooden pillar 13 and the cloth foundation 2.

In the base pad 1 of this embodiment, small-diameter projections 6 are formed at a plurality of locations around the plate-shaped main body 4 as gap-forming projections 5 and large-diameter projections 7 are formed at the center of the plate-shaped main body 4. It is provided with a dish-shaped root-winding member 15 made of a metal plate and a wooden plug 16. The dish-shaped root-winding member 15 made of a metal plate
It is fitted on the lower end of the wooden pillar 13 and is placed on the flat body 4 of the pad 1 for the foundation, and has a through hole 17 in the center part that matches the large-diameter projection 7. , Which is screwed and fixed to an anchor bolt 18 projecting from the cloth foundation 2, penetrates through the large-diameter projection 7 of the foundation pad 1 and the through-hole 17 of the dish-shaped root member 15, and It is press-fitted into a hole 19 formed at the center of the lower end.

According to this embodiment, the wooden pillar 13 is mounted and supported on the cloth foundation 3 via only the foundation pad 1 without passing through the wooden base 3, and the wooden pillar 13 is screwed and fixed to the anchor bolt 18. Since the stopper 16 is pressed into the hole 19 to completely prevent the horizontal movement, the connection with the cloth foundation 2 can be strengthened while simplifying the structure of the wooden building, and the foundation pad 1 is provided. , The load acting on the wooden pillar 13 can be transmitted to the cloth foundation 2 almost uniformly and smoothly over the entire lower end surface thereof. In addition, since the dish-shaped root winding member 15 is externally fitted to the lower end of the wooden pillar 13, the wooden plug 16 is inserted into the hole 19.
There is no danger of cracking at the lower end of the wooden pillar 13 even if it is press-fitted.

In this embodiment, at least the large-diameter projection 7 is provided.
It is necessary to form an annular wall having a central portion penetrated in order to allow the anchor bolt 18 to penetrate, but the small-diameter protrusion 6 may be formed in a cup shape with a bottom.

[0022]

The pad member for foundation of the present invention can be embodied as described above. A load acting on a wooden base or a wooden pillar is applied to the flat body of the foundation pad and the gap forming projection. Since it is supported by the cloth foundation, a stable supporting state can be obtained while forming a gap between the cloth foundation and the wooden base, and air is also provided between the gap forming protrusions at the pad for the foundation. Since it circulates freely, air permeability is ensured, and it is not necessary to increase the thickness of the foundation pad more than necessary and increase the height of the gap between the base and the cloth foundation. The opening area required for underfloor ventilation can be ensured while the gap between them is relatively small, and it is very effective in preventing corrosion of the wooden base.

Further, since the gap-forming projection is constituted by a bowl-shaped projection having an inclined peripheral wall, the bowl-shaped projection integral with the flat plate-shaped main body made of a metal plate is more supported than a rubber plate. Relatively high rigidity ensures a stable support state in normal times, and furthermore, when an impact load is applied during an earthquake or the like, the bowl-shaped projection elastically deforms and eventually buckles to support the buffer. As a result, the effect of dispersing and absorbing an excessive load to prevent fatal damage of the wooden building can be obtained.

According to the second aspect of the present invention, the gap forming projections include a plurality of small-diameter projections around the plate-shaped main body and a large-diameter projection in the center of which an anchor bolt can be inserted. Since it is provided, the load can also be supported at the center of the plate-shaped main body while also serving as the insertion portion of the anchor bolt, and the load can be dispersed and supported by the entire plate-shaped main body.

According to the third aspect of the present invention, since the gap forming projection is provided with a bottom and at least a through hole formed at the bottom, the support is stable at the bottom wall. In addition, dew condensation water and the like do not accumulate in the gap forming projections, and the cause of corrosion prevention can be eliminated.

Further, according to the structure of the fourth aspect, the dish-shaped root-winding member is fitted on the lower end of the wooden pillar and placed on the foundation pad, and is screwed onto the anchor bolt projecting from the cloth foundation. By pressing the fitted wooden stopper into the hole formed at the center of the lower end of the wooden pillar, the wooden pillar can be supported and fixed on the cloth foundation via the foundation pad only, without passing through the wooden foundation. , The structure of a wooden building can be simplified and the connection with the cloth foundation can be strengthened, and the load acting on the wooden pillar through the pad for the foundation can be distributed almost evenly and smoothly over the entire lower end surface. It can be transmitted to the foundation.
